May Measurement Month 2021: an analysis of blood pressure screening results from Republic of the Congo, in the context of COVID-19 pandemic.

Abstract

To determine the proportion of hypertension among opportunistic screenees in the Republic of the Congo, and the relationships between, blood pressure (BP), alcohol intake, and history of coronavirus disease 2019 (COVID-19). Screening was carried out in July and August 2021 in Brazzaville, Pointe-Noire, and Pokola, after ethical clearance had been obtained. The campaign followed the guidelines outlined in the MMM21 protocol, collecting ideally three BP readings for each participant. The screening was carried out during the partial confinement of the population, due to the COVID-19 pandemic. Social distancing measures and protection against the transmission of COVID-19 were adhered to. A total of 2135 subjects were screened of which 1138 (53.3%) were male. The mean age was 29.9 ± 9.9 years (range: 18-69 years), and 2110 participants (98.8%) were of black ethnic origin. A previous COVID-19 positive test was reported in 217 (10.2%) and vaccination in 93 (4.4%). Diabetes was reported in 113 (5.3%), 16 (0.7%) were current smokers, 171 (8.0%) reported using alcohol intake at least once per month, and 539 (25.3%) reported meeting the WHO guidelines on physical activity. The proportion of participants with hypertension (≥140/90 mmHg or taking BP-lowering medication) was 34.1%, of whom 24.5% were aware, 11.9% were on medication, and only 4.0% were controlled (<140/90 mmHg). Rates of hypertension are high in the Republic of Congo, with low rates of awareness and treatment, and national authorities should address the contributing factors highlighted in this report to improve health care for the population.
